i KNITTING-MACHINE ATTACHMENT.

To aZZ whom it may concern.-

Specification of Letters Patent.

an extremely simple and inexpensive, yet a highly eflicient attachmentfor knitting machines of the cylinder type which will absolutely preventany oil on the cylinder or on the inner side of the usual dischargesleeve extending below said cylinder, from soiling the knitted product.a

A further aim is to provide a device of the character set forth whichmay be used in connection with well-known knitting machines, without thenecessity of making any alteration in the construction thereof.

With the foregoing in view, the invention resides in the novelconstruction and association of parts hereinafter described and claimed,the descriptive matter being supplemented by the accompanying drawings.

Figure 1 is an elevation of a knitting ma chine equipped with one formofmy invention, a portion of the latter being in vertical section.

Figure 2 is a vertical sectional view as indicated by line 2-2 of Fig.1.

Figure 3 is a horizontal sectional View as indicated by line 3-3 of Fig.2.

Figure 4 is a view similar to Fig. 1 but showing a different form of theinvention;

Figure 5 is a vertical sectional view on line 55 of Fig. 4. a

Figure 6 is a detail horizontal section on line 66 of Fig. 5.

Figure 7 is a perspective View of the at tachment shown in Figs. 4, 5and 6.

In the drawings above briefly described, I have shown a well known formof knitting machine which comprises a table 1' supporting the usualcylinder 2 and its driving gear 3. The needles are designated by the-nu-' meral 4 and their operating cam is indicated at 5, these severalparts being operable in the well known manner to'form a knitted product6 which is usually discharged through. a sleeve 7 secured to the table 1and depending therefrom., Proper lubrication oi. the nee- Patented Feb.7, 1922.

dles 4 and associated parts often causes a] quantity of oil tocollect onthe inner side of the cylinder 2 near its lower end, and some of thisoil runs down the inner side of the sleeve 7, so that there is danger offorming oil spots on theproduct 6, as it is discharged.

This is very undesirable since any portion of the product which isoil-soaked will not properly take the dye when the dyeing open ation isperformed. Oil-snotting of the product is prevented by my invention,which I have shown in twoforms for knitting short or long hose or thelike. In Figs. 1, 2 and 3, the numeral9 designatesa vertical elongatedcasing received within the sleeve 7 and provided at its upper end with.a neck 8 extending upwardly into the cylinder 2 so as to receive theproduct 6 and guide it into the casing 9 without permitting said productto contact with the cylinder or with the sleeve 7. The casing 9 isrelatively long and isintended for use when'long hose or the like isbeing knitted and the casing in question is preferably increasedgradually in size at its lower end, which end is equipped with alaterally extending portion 9 whose top formed with an opening 10 bymeans of which the work may be removed. A flange 11 inclines from theinner edge of the opening 10 and serves to prevent any oil which mightpossibly accumulate on the top of the extension 9 from entering thecasing through the opening 10.

Any suitable means may be employed for secur ng the attachment in place,but I prefer to equip it with a pair of metal strips 12 and 13 throughwhich screws 14 are passed, said screws being threaded into the lowerend of the sleeve 7.

Figures 4 to 7 disclose the form of my invention which is employed whenknitting relatively short work. In these figures, the

numeral 20 designates ,a vertically elongated casing positioned totallywithin the sleeve 7 and provided with a reduced inlet neck 21 to extendupwardly into the cylinder 2 as shown in Fig. 5. 7 One side of thecasing 20 is provided with an opening 22 for registration with the usualopening 23 in the sleeve 7 and the uppermost and vertical edges of saidopening 22 are provided with metal flanges 24 (preferably formed oflead) which are adapted to be bent outwardly along the correspondingedges of the opening 23 (see Figs. 5 and 6). These flanges form guardsto prevent any, oil running down the inner sideof the sleeve'7, frompossibly entering the casing 20 through its opening 22. One ofthefianges is secured to the sleeve 7 by appropriate screws 25. I V

From the foregoing, taken in connection with, the accompanying drawings,it will be seen that I have provided a very simple, yet 'a highlyeflicient and desirable device to abmay be made. F urthermore,foradapting the attachment to difierent types of ma chines, itmay bemanufactured in numerous forms other than those disclosed. a

I claim:

1. The combination with a knitting ma chine, of a receiving casingforthe knitted product having an inlet neck extending upwardly into thecylinder of said machine to prevent the product from coming in contact;

with any oil on said cylinder,-saidcasing having a closed bottom and anoutlet open ing, and a guard to prevent any oil on the exterior of saidcasing from running. into the latter through said opening.

2, The-combination with a knittingomaa chine having a sleeve extendingbelow'its cylinder and provided with an opening in one side, of areceiving casing for theknitted; product positioned in said sleeve andhaving sleeve opening.

,an opening registering with the aforesaid opening, and flanges on saidcasing bent outwardly around the edges of said first named opening, saidcasing having an inlet neck extending upwardly into said cylinder of theknitting machine.

3. An attachment for knittin machines k:

comprisinga receiving casing for the knitted product having an outletneck adapted to'extend upwardly into the cylinder of a knitting machine,said casing'ha'ving a closed bottom and being provided with an outletopening, and a guardto prevent oil on the exterior of the casingfrom'running into said casing through said opening, I a v 4. Anattachment for knitting machines 1 comprising a verticall elongatedtubular casing having an inlet neck at'its upper end 1 1 adapted toextend upwardly into the ,cylin der of a knitting machine, said casingbeing adapted for reception in the usual sleeve of the machine andhaving an outlet opening for registration withan opening in theaforementioned sleeve, and a flange on said casing at the edge of itsopeningtadaptedto be bent outwardly around the edge ofthc In testimonywhere my hand. a I g a his 7 GEORGE X W.
